Specification forming part of LettersPatent No. lS9,l32, dated April 3, 1877 application filed February 10, 1877.

To all whom it may concern Be it known that I, DANIEL NYSEWANDER, of Springfield, in the county of Clarke and State of Ohio, have invented a new and useful Improvement in Windmill, of which the following is a specification:

Figure 1, Sheet 1, is a side view of my improved windmill, partly in section to show the construction. Fig. 2, Sheet 2, is a detail view of the automatic adjusting. mechanism. Fig. 3, Sheet 2, is a front view of the windwheel.

Similar letters of reference indicate corresponding parts.

The object of this is to improve the construction of the windmill for which Letters I Patent No. 181,196 were issued to me August 15,1876, so as to make it more effective in operation and enable it to be more efl'ectually controlled.

The invention consists in the combination of the two segmental gear-wheels, the two regulating-vanes, and the adjustable weight with the turn-table and the main vane; in the combination of the flaring flanges with the edges of the wings of the wind-wheel in the combination of the brace-bars with the flanges and the wings of the wind-wheel; and in the combination of the upright bar, the cross-bar, the hinge-bar, and the two brace-bars with the turn-table and the vane, as hereinafter fully described.

A is the turn-table, upon the lower side of which is formed a long hollow spindle, a which passes down through a sleeve or socket, B, and is secured in said socket, and at the same time allowed to revolve freely, by a set-screw, b, passing in through the upper part of the said socket B, and entering a ringgroove, in the said hollow spindle a. The socket B has a ring-flange formed around it near its upper end, which rests upon and is secured to the top of the frame or tower 0. Upon the forward side of the turn-table A is formed an arm, a, to receive and support the shaft D. To the shaft D is secured the hub of the wheel E, which is formed by slitting a square plate of sheet metal of suitable size from its corners nearly to its center, and bending one of the two points thus formed at each corner forward, and securing it to a collar or head attached to the outer end of the shaft D. To the curved edge of the wings of the wheel E are attached flaring flanges e, to present a larger surface to catch the wind. To the outer edges of the flanges c of the wings of the, wheel E are attached strips 0 which, at

or near the inner ends of said flanges, are bent outward, pass around the bases of the wings,

and are attached to the hub of the said wheel, to serve'as braces to strengthen the wheel E. To the inner end of the shaft D is attached a small crank-wheel, F, to the crank-pin of which is pivoted the lower end of the connecting-rod G. The upper end of the connecting-rod G is pivoted to the inner end of the arm H, the outer end of which is pivoted to the. upper end of the bracket'I. The lower end of the bracket 1 is secured to ,a projection or lug formed upon the turn-table A.

The arm H is made of such a length that its inner end may be directly over the cavity of the hollow spindle a and to said inner end is pivoted the upper end of the rod J, which passes down through the cavity of the said hollow spindle a, and with the lower end of which is connected the pump or other machinery to be driven.

Upon the turn-table A, directly opposite the wheel-bracket a, is formed an arm or bracket, a", to which is pivoted a segmental bevel-gear wheel, K, the teeth of which mesh into theteeth of a segmental bevel-gear wheel, L, pivoted to an upright arm, M, formed upon the turn-table A. To the segment K is attached the main vane N, and to the segment L are attached the stems of two vanes, O P, which project upon the opposite sides of the turntable A, .and are set at such an angle that the wind may tend to turn them toward the main vane N, and throw the wheel E out of the wind. To the stem of the vane P is adjustably attached a weight, Q, of such a size as to hold the wheel E to the wind until the wind has increased in force beyond a certain point. If the wind should still further increase in strength, the wheel E will be turned. entirely out of the wind, and will stop. When the wind decreases in force the wheel E will be again turned into the wind by the action of the weight Q.

Tothe weight Q is attached a cord or chain,

R, which passes over a pulley, S, pivoted to the cross-bar W. The chain R, or a rod attached to said chain, passes down through the hollow spindle a and is attached to a sleeve, T, through which the rod J passes, and to which is swiveied a ring, U. To the swiveled ringUis attached the end of a cord, V, which extends down into such a position that it may be conveniently reached and operated by the attendant to raise the weight Q, throw the'wheel E out of the wind, and

stop it when desired. To the upright arm M is attached an upright bar, m, to the upper end of which is attached a bar, W. In the rear end of the bar W is formed a hole, to re ceive the hook formed upon an arm of the U- bar Y, the other arm of which has a hole formed through it to receive the end of the brace-bar X. The bar Y thus forms a hinge for the brace X, which is attached to the vane N, so that the said brace, while strengthening and supporting the said vane N, will not interfere with its movements.

To the forward end of the bar W is attached the end of a brace, Z, the other end of which is attached to the arm a, that carries the shaft D.

Having thus described my invention, I

claim as new and desire'to secure by Letters substantially as herein shown and described.

3. The combination of the bars 6 with the flanges e and. the wings of the wheel E, substantially as herein shown and described.

4. The combination of the upright bar m, the cross-barW', the hinge-bar Y, and the brace-bars X Z with the turn-table A and the vane N, substantially as herein shown and described.
